In vitro propagated Patharnakh shoot-tips were grafted on in vitro propagated Kainth rootstock. Graft success, occurrence of necrosis and vigour were found to be influenced significantly by scion length, grafting technique and medium used for shoot tip grafting. Graft success was maximum (33.71%) by using L2 (5–10 mm scions), G1 (wedge grafting) and M2 (MS liquid media + 20 g/l sucrose). However, necrosis was least (0.0%) in many treatment combinations. Maximum vigour (2.68) was found by using L2, G1 and M2.
